This invention relates to a sash window and has for its primary object to provide, in a manner as hereinafter :set forth, a window of such class in which the sashes may be ,6 readily swung to angular positions with .re-

spect to the frame to facilitate the cleaning of the sashes and to obtain greater ventila tion "than :is possible in sash windows of or- .dinary construction.

1 7. VA further object of the invention is to provide :a sash window of the character aforesaid in which the sashes are provided with pins slidable relative to the frame for pivotally supporting thezsashes when the lat- 15 ter are zangularly extended with respect to the frame and in which the pins serve as antirattle devices when the sashes are normally disposed withrespect to the frame. 7 i

- With the foregoing and other objects in 29 view, the invention consists of thenovel con- -.struction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but :it is to be understood that the description and (drawings :are to be taken as illustrative and that the invention is intended to be limited only by the scope of the claims hereunto appended.

In the accompanying drawings in which like numerals are employed to designate like parts throughout the several views: 7

Figure 1 is a sectional, front elevation of asash window accordance with this inven- 35 .tion, the View being taken substantially at the point indicated by the line ll of Figure .3.

Figure 2 is a vertical section through the window showing the sashes in angular rela- 40 tion tothe frame.

' Figure 3 is a vertical section through the window showing the normal position of "the sashes with respect to the frame.

Figure 1 isa horizontal section taken at '45 the point indicated by "the'l ine of Figure '3. V

Figure 5 is an enlargedfragmentary sectiona'l elevation of one of the sashes and one of the inner side members -:of the frame.

Figure 6 an enlarged perspective view of the removable portion of one of the dividing-strips.- V 1 v Figure? is an enlarged fragmentary section through the removable portion of one of the dividing strips and through one of the inner side members of the frame. Referring to the drawings in detail, the numeral 1' indicates generally a window frame formed, at its sides with inner side members 2 and outer side members 3 which are connected together by means of rear members 4; :and front members 5 to provide the usual weightachambers '6. Forwardly of the front members 5,, the frame is provided with the usual facing strips 7', the members 2, 8, 4, 5 and 7 being seated in the usual manner on .a sill 8.

s ,Sh da-bly mounted between the inner frame members 2 is an upper sash ,9 and a lower :sash 1 0. The :rear members 4 project inward- :ly beyond the inner side members 2 to pro-- vide abutments for therear face of the upper sash a9. Centrally thereof, the .side members 2 are formed in their opposing faces with vertically extending grooves 11 within the "upper portions of which are secured stationary dividing stripportions 12, and within the lower zportionsof which are positioned removable dividing vstrip portions 13 in vertical alignment with the portions 12. The

isltripsilQ :and .13 provide abutments for the forward face of the upper sash 9 and for the rearward face of the lower sash 10. The lower sash 1.0 is abutted at its forward face by -stationary retaining strips 14 secured to the front members 5, and :by movable retaining strips 15 which are hinged to the front members 5 :and which normally extend in vertical alignment with the strips 14.,

Embedded in theinner side members 2 and front members .5 are a pair of'plates 16 which are formedwith slotsl? forwardly Y and upwardly curved at their lower ends. In alignment with the slots 17 the side members;2:.ar.e formed with grooves 18 which are substantially of greater area in cross section :than the width of the :slots and which gradually decrease in depth in an upward direction from a point in spaced relation toythe upper ends of'zthe plates 16. Adja-' cent each side thereof, the lower sash 10 is through the slots 17. Each plunger 22, is resiliently forced outwardly by means of a spring 24 which encircles theplunger, and

the respective ends of which abut one of the lugs 20 and a pin 25 extending through the plunger and located betweenthe lugs. The outer ends of the plates 21, as well as the side faces of the sash 10, are recessed as indicated at 26 for the receptionof the sash portion 27 for' the sash 10. The plates 16 are disposed at a proper height to position the plungers 22 within the slots 17 when the, sash 10 is in its lowered or closed position as shown in Figure 3. 1 a V 7 Embedded in the side members 2 and rear members 4 are a pair of arcuate plates 28 which are formed with arcuate slots 29 which curve upwardly at their lower ends. In alignment with the slots 29 aregrooves 30 in the side members 2, the grooves 30 being of substantially greater cross sectional area than the width of the slots 29. Projecting from the side faces of the upper sash 9,

adjacent the upper face of-the latter, are,

plungers 31 similar inevery respectto the plungers 22 heretofore described.- The plungers 31 are adapted to extend through the slots 29 and to have the heads thereof slidablydisposed within the grooves 30. The plates 28 are arranged below the plates 16 and are of a proper height to receive the plunger-s 31 through the slots 29 when the upper sash is in its lowered or opened position. r

' The removable dividing strip portions 13 extend across the plates 28 and are provided in their outer side faces with notches 32 for the reception therein of the plates. The portions 13 are maintained in position by means of headed pins 33 which depend therefrom into recesses 34 in the sill 8, and by means of latch plates'35which are provided centrallythereofwith resilient, split tongues 36 which frictionally engage central portions 37 of latch members 38 secured to the side members 2 and which extend across and conform incontour with the walls of the grooves 11. The central portions 37 of the members v33 correspond incontourto the tongues 36 on the latch plates 35. i

"Extending through suitable openings in the facing strips 7 are a pair of chains 39 which are provided at their outer ends with hooks 40, and which have suitable weights 41 nsuaisv shown in Figure 2, and the sash is raised a sufficient distance to clear the abutment strip I 45 seated on'the'sillj8, The lower end of the sash then may be swung in a forward and upward arc, causing the plungers 22 to ride along'the slots l7 and enabling the sash to be inverted with'the outer face thereof disposed inwardly." v I o 1 i If it'is desired'to clean the outer face of the upper sash 9, the. removable dividing strip portions-13 are removed and the sash 9.is slid downwardly with respect to the frame, after which the lower end-thereof may be swung in a forward and upward arc in the same" manner j as above described in connec tion with the lower sash 10. The upper sash 9 may be swung at an angle with respectto the frame either with'the lower-sash 10 in an angular position'as shown in 'Figure 2 or in its normal open positionbetween the retainv ing strips 14 and the stationary dividing strip portions 12. If it is desired' to anchor either or both of the sashesin angular relation to the frame, this may be accomplished simply by engaging the hooks 40 of the chains 39 with the hooks 42 of the sashes. a

- It is thought thatthe-many advantages of a sash window in accordance with this invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangement of parts may be resorted to, so

longas such changes'fall within the scope of the invention as defined in the appended claims. l

What'I claim is V. I. A sash window comprising, a frame, an

upper and a lower sash slidable in the frame, f

plateshaving arcuate' slots connected with the frame, andplungers projecting from the sashes intosaid slots for pivotally'connecting the sashes with the'frame, said frame having grooves, said plungers having resilient means a for forcing the heads towards the frame.

2. A sash window comprising, a frame,

I spring pressed plungers projecting from o'pposite'sides of each sash into engagement with the framepsaid-frame having arcuate' grooves for receiving said plungers to pivotally connect the sashes with the frame.
